Abstract

The present disclosure provides a roller and a locking method thereof. The roller includes a main body, a first groove provided on an inner surface of the main body, and a first elastic component fitted with the first groove; wherein a through hole for receiving and fixing a shaft is provided on the first elastic component. The present disclosure can be used to lock shafts.

First claim

The invention claimed is:

1. A roller, including
a main body,
a first groove provided on an inner surface of the main body,
a first elastic component fitted with the first groove; and
a second elastic component, which is provided to surround an outer surface of the main body;
wherein a through hole for receiving and fixing a shaft is provided on the first elastic component, the through hole of the first elastic component is configured to sleeve the roller to a required locking position on the shaft, the first elastic component is in direct contact with the shaft, and the first elastic component and the shaft are fitted with a manner of interference fit; and
an inner diameter of the first elastic component is smaller than a diameter of the shaft by 2 mm, when it is required to adjust a locking position of the roller on the shaft, the roller is directly pushed to an adjusted locking position on the shaft to complete re-locking to the shaft.

2. The roller according to claim 1 , wherein the inner surface of the main body is provided with two of the first grooves.

3. The roller according to claim 1 , wherein a shape of the first groove is selected from a group consisting of a circle, an ellipse, a triangle, and a rectangle.

4. The roller according to claim 1 , wherein a material of the first elastic component includes rubber.

5. The roller according to claim 1 , wherein the second elastic component is completely wrapped on the outer surface of the main body.

6. The roller according to claim 1 , wherein a second groove is provided on the outer surface of the main body; the second elastic component is embedded in the second groove.

7. The roller according to claim 6 , wherein the second elastic component protrudes from the second groove.

8. The roller according to claim 1 , wherein a material of the second elastic component includes rubber.

9. The roller according to claim 1 , wherein a material of the main body includes plastic or metal.

10. A locking method for a roller as claimed in claim 1 , including:
embedding and fixing the first elastic component in the first groove provided on the inner surface of the main body; and
sleeving the roller to a required locking position on the shaft through the through hole of the first elastic component.
